UNITED STATES- rara JOHN BURRY, OF RDGEFIELD PRINTING-TELEGRAPH RECEIVER.E

Application ledMarch'', 1906; Seria1No. 368,954.'

To all 'whom it may concern."Y

Be it known that I, Jox-IN Burani', a citizenV of the United States, residing at Ridgefield Park, in the county of Bergen andiState of" hcw Jersey, have invented certain `new and" useful Improvements in Printing-Telegraph Receivers, of which the following isa speci` ication, reference being hadto the drawings a ceompanying and formingpart of thesame.

lMy invention relates-.to receivingl devices for `,printing telegraph systems, and hasfor its object to provide a receiving-apparatus of.

, the utmost simplicity of construction and certainty ofv operation, so that the same may be used by unskilled persons, and in places where the. apparatus will be subjected to se vere vibrations or shocks.

Attempts have been made in the army andV navy'to utili/ze printing telegraphs to supply to gunners thepdata found by a distant *range finder, but it has been found` that .the

systems commonly in use'are too delicate in construction to withstand the severe usa e to which the apparatus is unavoidably su ijected. The receiver must of course be located near the gun which the gunner-s are serving, and consequently the concussion and vibration produced by the discharge of the gun are communicated to the receiver, result- -lng in frequentl derangement of the same.

My object has therefore been to provide a receiving apparatus which shall loe able to withstand such usage indefinitely and to operate with certainty and precision at all times.

The most important feature of myA invention resides in`tl1e ein loyment of a type plate, as distinguished rpm 4the usual wheel or cylinder, which plate is .by meansof suit-- able magnets under the control of the distant transmitter shifted'laterally and longitudinally to bring any selected character -to the impression point or printing position.. In the preferred embodiment fof thek invention the type'plate'is-carricd at the endof a bar or lever which'is capable of oscillation on either of two fulerums at `will, and also of 'heilig shifted laterally and longitudinally.

The use,I of two fulcrnins gives tivo oscillations, and the lateral shifting of the lever ives a third movement, 4from the normal o r vinitial position of the'type plate. ln this any v of four longitudinal rows of type on the plate may beselected for printing. Between the two fulcrums a second arm or Speclpation of Letters Patent.

'l lever is pivoted to the first, substantially at right anglesy thereto' this 'second lever being Yalso capable of oscillation ontwvofulcrums .and of being shifted longitudinally and transversely. These movements. of thesec-jL pendentl circuits. Thesel magnets 4may-flicl gized at-nll, giving-by. simple permutation, the sixteen different positions oflthetype plate. ln the rpreferred ,constructionthe magnet armatures carry 'the fulcrums ofthe levers, so that when o ne fulcrum vorpivotis for oscillating the lever, whileenergization of both magnets on the y'saine'.lever causes the lattervto beshifted bodilyina trans# verse direction. l t

The impressions are :made preferablyon a.' tape, drawn longitndinallyover the printing point by suitable mechanism., .In .the form herein illustrated the print-ing and the feed of the tape are effected by -theageneyof aj [fifth magnet, in fifth circuit.` x,

lt will be apparent to those skilledin the 'art that thevscheme above outlnedanay be lthe same may be -employed for a great,variety` of purposes.

A. simple and convenient embodiment,if,deL signed more part1cular1y.,.f or the n artillery. service above mentioned, 1s lllustrated in adjustment of the type 'plate to bring se* -1s a table 5 and leeted characters to the printing point. Fig. 13 is a simple diagram showing the wiring of the system.

The various parts of the apparatus are conveniently mounted on a'base plate 1.

Rising therefrom are three standards or` in, is a second lever, 15. The latter has longitudinal slots 16, 17, arranged as those in the first lever, over transverse slots 118, 19 inv the extension 6. Pins 20, 21 project upwardly through these slots, as in the former case.

Carried at the forward end "of the lever or arm'7 is a type plate 22, on which, in the present instance, are sixteen characters, arranged in four straight longitudinal rows and four curved or are-shaped transverse rows. The type plate andthe arrangement of the characters thereon are clearly shown in Figs. 1 and 4, the longitudinal rows, that is,the rows which extend longitudinally of the lever 7, being designated by a, b', c, d, respectively, and the transverse rows by a', b', c', el', respectively.

f Immediately below the type plate, and movabley upward through an opening in the end of the table, is a vertical pin or bar 23, (see Fig. 5),y adapted by its vertical movement to carry the type plate upward against a paper strip or tape 24. Under the type plate, the

latter is an' inked tape and ribbon 25, and.

above the ribbon is a'platen 26, having a flat boss 27 directly over the pin or barY 23.

Consequently when the latter rises the paper and inked lribbon will be struck against the f platen and an .impression on the paper will bemade of whatever type or character is at the impression point, that is to say, directly over the bar 23` and under the boss 27.

ll/Vith the ink ribbon running between the impression tape' and the platen, the latter soon acquires va thick, rounded or convex layer orl coating of ink, the convexity of which confines the impression to the central portion of the type, leaving the outcr'portions untouched, and thus producinga confusing or even illegible imprint. l3nt with the'ribbon running'between the tape and the latennever comes in contact with the rib on, and hence is kept clean.

However, arranging the ribbon below the tape causes the impressions to be made on the under or unexposed side of the tape, as will be readily understood; but it is doeii`- able, particularly in the artillery service mentioned, that the impressions be visible as' fast as printed. .l lsecure this result by using a tape which is at least translucent, preferably as nearly transparent as possible, so that the impressions, though made on the unexpos'ed side of the same, are yet clearly readable through the tape.

As previously stated, the type plate is shifted'longitudinally and transversely to bring any desiredfletter to the impression point. This shifting of the plate effected as follows, referring to Figs. 1 and i-12.

The initial position of the plate is shown in Figs. 1 and (i, with the dash, which is in rows b and Z2', at the impression point. The pins 12 and 1.3, extending through slots l1, 9, and 10, 8, respectively, ctnistitute fnlerums, normally fixed but movable simultaneously, and independently. lf the mag net 28, hereafter more fully described, be energized, it will draw the pin 13 over, as in Fig. 7, throwing the type plate to the right, until the pin 13 strikes the left end of slot 11, and bringing row a to the impression point above the bar or plunger 23. ln this movement the pin 12 acts as the fixed fnlerum, while the other, 13, swings the lever. lf now magnet 29 be energized, or both magnets simultaneously, both pins will be drawn over and the lver 7 will be shifted bodily; to the left, such movement being permitted by the slots 16, 17, in the arm 15, bringing row oto the` impression point, as in Fig. 8.

lf only magnet 29 be energized the pin 13 will act as the fulcrum and pin 12 will draw the leverto the left. and since the fulcrnm is now at the end of the lever the swing ot the latter will be longer, and will lin-ing row to the impression point, as in Fig. ln this way any of the longitudinal rows u, L, c, (l may be brought to the printingl position. As already stated, row Zi, of the transverse rows, is normally at the impression point. lf now magnet 30, Fig. 10, bc energized, pin 20 willdraw the outer end of the lever down, on pin 21 as the fulcrum, and retract lever 7 and with it the type plate. lningingl transverse type-row a over the bar Q3. lt ning nets 30 and 31 are both energized the arm .15 will be shifted bodily downward. bringing row c to the impression point, as in Fig. 11. vEnergizing magnet 3l alone will givtI the arm 15 a longer sweep. and bring row d over the printing bar 23. Any ot these movements of the arm l5 may be combined with any movement of the lever 7. so that any chai-acteren the plat@ an be brought to the impression point, as will be reatily, understood.

plate is limited by the-pins-striking the endsl of the slots in the table 5 and: extension 6, so

that the position of the'plateis always aci-.

curately determined.

As previously stated', the pins 12, 13, 20,.y

21 are carried by armature'levers, indicated by 32, 33, 34, 35,respectively, arranged to be actuated by the magnets 29, 28, 30, 31, respectively. These magnetsl aremounted on the base l, and.` their armature levers are pivoted in front ofA them.` -The armatures' are normally retracted, tol thev position ofl Fig. l, by-Springs36, 37., 38,..39,.wliich` en-` with their respective armaturesifby` links-44, 4.5,"46, 47; It` will be seen that bythis method eacharmature isyieldingly held in and to'secure this result the pole pieces of its normal position with some` degreey et lirmness, so- 'as not tol be disturbedby' thev other magnets. Each armature, however,`

n i yields to its' own magnet, andby reason offf 'the arm connecting" it withV its sprinefv thel force of the latter immediately diminishes lt is therefore necessary that-'magnets exert their maximum force'as the armatnreszstart,

the magnets are extended-so that thev arma'- tures move. betweeny them, as clearly shown, for example, in' Fig. 1i. By this construction each armature olers maximum resistanceto movement by other magnets` than. its own,

et moveswith diminishincresistance when` its own magnet is energized, The .operation of themachine is lthus made positive and sui-e at all times.

To effect the printing avertical magnet 48 is provi ed, on the end of whose armature lever 49 the printing pinl or bar 23 1s mounted. The armature 49 is pivoted at the top of a standard 50, so that energiza.-

tion of the magnet will'raise,thefprinting pin against the4 tensionoffthe .spring 51.

The tape 24, on which the impressions are made is .carriedin i aj roll on 'a reel .'52,- mounted on' the post 4, and passes upwardly over and incontact with a,scape wheel 53,' carried by arms 54 depending'from the table 5. The scape wheel `is facedon its'periphery with a friction-material, suchfaSSOft rubber, so that the pull of lthe tape will rotate the wheel. Projecting laterally from the wheel,

near its periphery, are equally spaced pins or teeth, 55', `the spaces. between the teet-h being equa-l to the desired. spaces between successive. impressions 4on the tape.. Projecting from the levery 49 at one side of the scape wheel is an arm 56, having at its end a notch 57, theoutei: ,side of. which: is., formed by' an upwardly projecting lug ortstop 58.

Extending forwardlyl and-laterally fronrthe lever 49, and into the `notch 56, is a-spring stop 58 is a stud 60, leavinoa'space-below- `the finger 59 wide enough .to pass. lThe operation of tliisesca'pement' for` the yteeth 25 5 is las follows: The tape, 'under constant ten-` sion, keeps the parts normally in the position shown in Figs. 2 and 3, the armature'49 having retracted the printing pin or hainmerl` 23. When the armature' 4is raised to produce an'y impression, the's'pring lingeris.

The. wiring ofthe system is illustrated diagrammatically in Fig. 13. In this ligure 28, 29, 30, 31, 48 represent the same magnets as in the other figures, and it will be seen that each magnet is vin an independent circult, controlled by its own key. It is clear, however, that by the use of suitable controlling devices 'the various magnets could be.

operated by three, two, or even one circuit. For'example, in my co-pending application Serial No. 233,484-, now Patent No. 785,110, issued December 31, 1907, I have described a system Ain which four selecting magnets The invention'is herein described, for con- 'telegraph sys-l venience, as part of a printin tem, but it is not confined to t e actual printing of characters, since it may be used to give intelligible signals .by the mere movement of the type plate or a member corresponding thereto, according to a prearranged code, or in other ways.
